eliminated the only user of cdev_index().  So it can be removed too.

Dave Anderson ceff1a7709 /proc/kcore: fix seeking
Commit 34aacb2920 ("procfs: Use generic_file_llseek in /proc/kcore") broke
seeking on /proc/kcore.  This changes it back to use default_llseek in
order to restore the original behavior.

The problem with generic_file_llseek is that it only allows seeks up to
inode->i_sb->s_maxbytes, which is 2GB-1 on procfs, where the memory file
offset values in the /proc/kcore PT_LOAD segments may exceed or start
beyond that offset value.

A similar revert was made for /proc/vmcore.

page->_mapcount is in a union with the SLAB structure so for pages

Jesper Juhl 566538a6cf reiserfs: make sure va_end() is always called after va_start().
A call to va_start() must always be followed by a call to va_end() in the
same function.  In fs/reiserfs/prints.c::print_block() this is not always
the case.  If 'bh' is NULL we'll return without calling va_end().

One could add a call to va_end() before the 'return' statement, but it's
nicer to just move the call to va_start() after the test for 'bh' being
NULL.

Mikael Pettersson f670d0ecda binfmt_elf: cleanups
This cleans up a few bits in binfmt_elf.c and binfmts.h:

- the hasvdso field in struct linux_binfmt is unused, so remove it and
  the only initialization of it

- the elf_map CPP symbol is not defined anywhere in the kernel, so
  remove an unnecessary #ifndef elf_map

- reduce excessive indentation in elf_format's initializer

- add missing spaces, remove extraneous spaces

No functional changes, but tested on x86 (32 and 64 bit), powerpc (32 and

Vasiliy Kulikov 65329bf46b fs/select.c: fix information leak to userspace
On some architectures __kernel_suseconds_t is int.  On these archs struct
timeval has padding bytes at the end.  This struct is copied to userspace
with these padding bytes uninitialized.  This leads to leaking of contents
of kernel stack memory.

This bug was added with v2.6.27-rc5-286-gb773ad4.

Jan Kara 0f0a25bf51 ext4: fix trimming starting with block 0 with small blocksize
When s_first_data_block is not zero (which happens e.g. when block size is 1KB)
and trim ioctl is called to start trimming from block 0, the math in
ext4_get_group_no_and_offset() overflows. The overall result is that ioctl
returns EINVAL which is kind of unexpected and we probably don't want
userspace tools to bother with internal details of filesystem structure.
So just silently increase starting offset (and shorten length) when starting
block is below s_first_data_block.

Make the 9P_FS kconfig options subordinate to the 9P_FS kconfig symbol
in the menu presentation instead of them all being at the same level.

Alex Elder 92f1c008ae Merge branch 'master' into for-linus-merged
This merge pulls the XFS master branch into the latest Linus master.
This results in a merge conflict whose best fix is not obvious.
I manually fixed the conflict, in "fs/xfs/xfs_iget.c".

Dave Chinner had done work that resulted in RCU freeing of inodes
separate from what Nick Piggin had done, and their results differed
slightly in xfs_inode_free().  The fix updates Nick's call_rcu()
with the use of VFS_I(), while incorporating needed updates to some
XFS inode fields implemented in Dave's series.  Dave's RCU callback
function has also been removed.

Trond Myklebust 6650239a4b NFS: Don't use vm_map_ram() in readdir
vm_map_ram() is not available on NOMMU platforms, and causes trouble
on incoherrent architectures such as ARM when we access the page data
through both the direct and the virtual mapping.

The alternative is to use the direct mapping to access page data
for the case when we are not crossing a page boundary, but to copy
the data into a linear scratch buffer when we are accessing data
that spans page boundaries.

Josh Hunt d96336b05d ext2: Resolve 'dereferencing pointer to incomplete type' when enabling EXT2_XATTR_DEBUG
When I enable EXT2_XATTR_DEBUG in fs/ext2/xattr.c I get a build error stating
the following:

  CC      fs/ext2/xattr.o
fs/ext2/xattr.c: In function 'ext2_xattr_cache_insert':
fs/ext2/xattr.c:841: error: dereferencing pointer to incomplete type
fs/ext2/xattr.c:846: error: dereferencing pointer to incomplete type
make[2]: *** [fs/ext2/xattr.o] Error 1
make[1]: *** [fs/ext2] Error 2
make: *** [fs] Error 2

These lines reference ext2_xattr_cache->c_entry_count which is defined
in struct mb_cache. struct mb_cache is currently only defined in fs/mbcache.c.
Moving struct mb_cache definition to include/linux/mbcache.h to resolve the
issue.

Eric Sandeen a4ae309486 ext3: speed up file creates by optimizing rec_len functions
The addition of 64k block capability in the rec_len_from_disk
and rec_len_to_disk functions added a bit of math overhead which
slows down file create workloads needlessly when the architecture
cannot even support 64k blocks, thanks to page size limits.

Similar changes already exist in the ext4 codebase.

The directory entry checking can also be optimized a bit
by sprinkling in some unlikely() conditions to move the
error handling out of line.

bonnie++ sequential file creates on a 512MB ramdisk speeds up
from about 77,000/s to about 82,000/s, about a 6% improvement.

Joe Perches 055adcbd7d quota: Use %pV and __attribute__((format (printf in __quota_error and fix fallout
Use %pV in __quota_error so a single printk can not be
interleaved with other logging messages.
Add __attribute__((format (printf, 3, 4))) so format
and arguments can be verified by compiler.
Make sure printk formats and arguments match.
